of 4.7 percent, which is more than the rate of growth for
retail sales by utilities (3.1 percent). In the past, wholesale
trade has been dominated by utility purchases from
other utilities. In 1998, utilities purchased a total of 1,669
billion kilowatthours of wholesale electricity from other
utilities and a smaller but increasing amount (259 billion
kilowatthours) from nonutility producers (Figure 17).
Wholesale power sales by nonutilities to utilities and
wheeling (the transmission of power from one point to
another via a third party) by utilities have both grown
vigorously. Wholesale sales by nonutilities grew from 40
billion to 259 billion kilowatthours between 1986 and
1998, yielding an average annual growth rate of 16.8
percent. Wheeling, while not increasing as spectacularly,

grew at an annual average rate of 8.3 percent over the
same period. Utility sales to ultimate consumers,
wholesale sales by nonutilities, and wheeling by utilities
all grew more slowly between 1990 and 1998, with
annual growth rates of 2.2 percent, 12.6 percent, and 4.3
percent, respectively.
International Trade
In recent years, U.S. international trade in electricity has
returned to the levels of the mid-1980s (Figure 18). U.S.
trade is mostly in imports, which were more than three
times the level of exports in 1998. Most imports are from
Canada (99 percent of total gross imports in 1998) and
the remainder is from Mexico.
